Ernst PORTABLE ESATEST HARDNESS TESTER

Handy Esatest X operates according to the ERNST patented ESATEST® principle of hardness determination through electrical resistance. The diamond indenter can be compared to a little potentiometer, which, while gradually penetrating into the material, obtains all the data (load-hardness) during the whole phase of load application.

Ernst PORTABLE HARDNESS TESTER - STE/B

Patented Calibrated Pins System
Standard scales : HB30, N/mm², kg/mm²
Applied force causes penetration of the indenter into
surface with a load determined by a calibrated expendable shear pin.
Resulting accuracy is comparable to the bench hardness tester

Ernst AUTOMATIC OMNITEST HARDNESS TESTER

Omnitest is an automatic universal hardness tester for test methods such as Rockwell, Superficial Rockwell, Brinell and Vickers, conform to standard international norms. The characteristic shape reduces flections up to 3 times compared to other universal hardnesstesters, which leads to increased precision in hardness detremination. Omnitest is particularly suitable for laboratory use and for all
those companies whose fundamental production concern is quality.

Ernst AUTOMATIC Twin-X HARDNESS TESTER

TWIN X is a Rockwell automatic hardness tester with direct read out in Rockwell and Superficial Rockwell scales. Can test large and irregular specimens up to 420 mm height ( 950 mm with special extended column). Overhanging pieces can be clamped without any extra support. The 50mm indenter's stroke permits testing difficult-to-test parts without any adjustment. Most suitable for in-line applications.

Ernst BRINELL 20X LIGHT MICROSCOPE

Antares is the new ERNST 20X light microscope for BRINELL reading.
6 mm long scale - 0.05 mm graduations.Suitable for checking of mechanical components.
The built-in leds provide an excellent and even illumination of the Brinell indentation's edge, avoiding that ambient light reaches the impression and disturbs the reading. In this way, accurate and reliable results are ensured in any situation.
Rugged aluminium housing provides durability and great efficiency up to 50 hours continuous operation without replacing the battery (a lamp on the main body indicates that light is on). The scope is delivered complete with ring for improve
stability during testing and with stainless steel base for testing in tight locations.

Digital Brinell microscope
all these problems allowing quick, automatic, and accurate
readings with no operator influence on the measurement. The magnified indentation on the screen also permits detection of any defect in the surface finish or the indentation.
